Trying to telnet through ASA

Hi,

I am trying to telnet through ASA, not able to do it . Though logs says connection is allowed.

Please check attached File for details.

I notice that R2 & R3 are attached to the same subnet, which explains why they're able to connect. Since you see the connection permitted by the ASA from R1 to R3, we can tell that R1 has a route to R3. But does R3 have a route back to R1? Something like:

! on R3
ip route 192.168.3.0 255.255.255.0 192.168.4.1

If it doesn't, then the connection could be failing because the replies just don't know how to get back.

Hi david,

R3 has route to R1, I am able to ping R3 from R1(through firewall).
